Aircraft and other vehicle windshields are exposed to a wide variety of loads, one of the most dangerous being the impact of solid objects at high velocities. For aircraft of all kinds, a relevant load case is bird strike, happening mostly during the landing and take‐off phase of flight. It is vital that such events do not completely destroy the windshield, which can be made of different materials, for example glass, PMMA, polycarbonate and combinations of these materials joined by rubbery interlayer materials.
